Lagoon Nebula a.k.a M8/NGC 6523
- It's an Emission nebula with HII regions, i.e, an Interstellar cloud of ionised Hydrogen that emits Light
- High Energy photons emitted by the stars are the source for Ionization
- Presence of HII region means that Star formation has taken place in that region recently
Trifid Nebula a.k.a M20/NGC 6514
- This is an another interesting region : a combination of an Emission Nebula, a Reflection Nebula & a Dark Nebula
- The bottom Red Region is an Emission Nebula
- The upper Blue Region is a Reflection Nebula
- The Gaps separating the Lobes in the Emission Nebula is actually a Dark Nebula ( Dense Interstellar cloud that blocks the light in visible wavelengths emitted by objects behind it )
- The Name means "Divided in to 3 Lobes", named after the divisions in the Lower half
Other Notable Objects in the Image :
1. Webb's Cross a.k.a M21/NGC6531 - an Open Star Cluster
